Within a 200 metre range from receiver position.3. A maximum actual tank height of 3 metres.50 metre effective range (200 metre clear line of sight).4. Tank must be fitted in accordance with manufacturersguidelines & instructions.NB: Any radio frequency signal may be seriously inhibited ifpositioned underground.

2. TANK PREPARATIONSonic Advanced TransmitterNOTE: it is important to keep all items dry during installation.A) PRE-DRILLED TANKS.Option 1: There may already be a 32mm pre-drilled opening in the tank top and possiblya tube fitted. If so, remove the cover by undoing the two screws holding it in place, anddispose of the tube in accordance with local government guidelines.Option 2: There may already be a 2” threaded hole with a red cap screwed in to it If soremove the red cap and disregard.NB - Ensure the hole is a minimum DIAMETER 30mm.Ensure that the space beneath the Watchman Sonic unit is free of any obstacles andthat the ultrasonic beam path is clear of obstructions. (See Picture 2)Pic 230cmB) UN-DRILLED TANKSWhere drilling is required to fit the transmitter, choose a flat levelpoint that is at the same level and no lower than any opening atthe top of the tank (filling point etc.) (See Picture 3)Choose a suitable position for transmitterWARNING: If you are unsure if you should drill a tank pleasecheck with the tank manufacturer first.OutletOutletPic 3The Transmitter can’t sit at an angle as this gives an incorrectlevel reading on the receiver. Take care not to choose an areaon which water could gather i.e. a dent/depression or a positiondirectly above any restricted area inside the tank. (See Picture 4)Pic 4NB: For tanks with window corrugations or internal braces ensurethat the Watchman Sonic Advanced is not positioned above orwithin 15cm of the area of the WINDOW or the edge of the tank.If the Watchman Sonic Advanced is positioned over or close to theWINDOWED area it transmits incorrect readings to the receiver. (SeePicture 5) Ensure that the sonic path is clear to the bottom ofthe tank as per pic 2. When installed incorrectly on some windowedtanks the unit can experience false alarms as the oil level drops. It isimportant to ensure that the unit is positioned so that the ultrasonicbeam has a 30cm diameter clear area to the bottom of the tank.Positioning the unit too close to the tank wall or near a tank windowmay cause false alarms.Tank Braces1Tank Windows35Pic 5Drill a hole in the place that you have selected on the tank’s topsurface using a 32mm hole-saw. (shown in Picture 6)Warning: If you are unsure if you should drill the tank please checkwith the tank manufacturer first.Pic 6SonicTransmitter3. FITTING TRANSMITTER BASE (ONLY IF SUPPLIED)SonicTransmitterTFor tanks with pre-drilled holes. Ensure guidelines from points 5 & 6 are adhered to. Remove cap from the hole (Picture 7) and inserttransmitter base, ensuring the weather seal is securelyin place (Picture 8 & 9). Tighten the Watchman Sonic Advanced base (Part E) on tothe tank with 2 stainless steel self-tapping, counter sunkscrewssupplied (Part C). Do not over tighten!Pic 730cm2Pic 8Pic 930cm30cm

4. FITTING THE BUND SENSOR (OPTIONAL)Having followed the steps 1 to 3 in the instructions theWatchmanSonic Plus receiver should be fitted on the inner tank.The leak detector should hang 5cm above the bottom of the outertank in the interstitial space of the outer tank as shown on thepicture above. To avoid the leak detector resting on the bottom ofthe tank, adjust the cable length using a cable tie provided.Note: It is imperative that the leak sensor is positioned verticallyabove the floor on the inner tank and that the cable is fixed toavoid any slippage or lengthening of the cable. Length of the cablecan be adjusted using the cable tie provided.WatchmanSonic PlusOuterTank(Bund)Lay 5cm above theouter tankLeakDetectorInnerTankPic 10OuterTankSonic HeightInnerTankFluid HeightInner Tank HeightTank HeightBunded Oil Tank Height does not include the base/piers which tank sits on.Single Skin Oil TankAccurately measure the height of your tank making noteof this measurement. The permissible maximum tankheight is 3 metres from the base of your tank to the positionof the Watchman Sonic Advanced (which should be no lowerthan the fill point). (Seen in Picture 11).Sonic Height5. DEFINE THE SONIC HEIGHTPic 116. SETTING THE SWITCHES ON THE RECEIVERUsing the tank height chart (see section 10), read across to therelevant multi switch settings using tank measurement you tookearlier. The multi switches are located in a recess at the back of thereceiver above the pins.Using a screwdriver or tip of a ballpoint pen,flip the relevant switch (e.g.) upwards ( ON).NOTE: If switch 1 is ON, it enables Sudden drop alarm. Thisfunctionality is valid only when used with advanced transmitters.If switch 2 is ON, it enables Waveguide mode, this functionality isvalid only when used with advanced sonic transmitters.Pic 12HOW SUDDEN DROP WORKSThe Sonic Advanced transmitter on tank checks the oil levelapproximately once every minute. Under normal conditions itcommunicates this level to the receiver approximately once everyhalf hour. In the event that a level outside the predefined thresholdtrigger level is reached in a given period (approximately 1.5cm perhour) the on tank transmitter sends a signal to the receiver and analarm will be set off on the receiver unit. In alarm mode the receiverunit will emit a siren type sound and the 10 bars will appear on thescreen in sequence. The red LED will also flash. This can only bereset by plugging in and out the receiver unit from the mains. Themaximum permissible usage of oil that the unit will allow in heightterms is 1.5cm per hour. This is the maximum rate that the level candrop in one hour without the alarm going off.WARNING:- Alarm and level functionality will be disabled if the unit detects a noecho condition (ref: section 11 - Technical Information). The no echocondition is indicated by a triangle symbol in the centre of the screenwith a line to the right of it. The no echo condition can be caused bythe unit being incorrectly installed on the tank, alternatively it canindicate in some instances that the unit has been moved or removedfrom the tank. An audible alarm can alert the user that a no echocondition or a transmission not heard condition has occurred (Referto trouble shooting for explanation of these conditions). Please notethis is not a tamper alarm and should not be used as such.- The alarm functionality at ullage levels of less than 25cm isdisabled. Therefore if a leak or theft occurs when the oil level is closerthan 25cm to the Watchman Transmitter on tank unit the alarm willnot go off.- In the event that the on tank unit detects a level drop there maybe a delay in sending the information to the receiver. This delay is toenable validation and protect against false alarms.- This product is to be used only on domestic oil tanks within theparameters outlined in the specifications. Any use of the product onapplications that lie outside a domestic environment is done so atusers own risk.WAVEGUIDE MODEWaveguide mode (pipe) is used in case of incorrect readingsor false alarms caused by installation problems. Lack of 15cmclearance from obstructions or flat (level) space on the tankto install transmitter. It required additional holder and pipeinstallation.

7. MATCHING RECEIVER & TRANSMITTERYou should match the receiver (Part A) with the transmitter (Part C)so that the system code is unique to your tank. Plug receiver into asuitable and convenient electrical socket and switch on.The display screen (Pic 13) on the front of the receiver will show aflashing top bar as shown in diagram. This indicates that the receiver iswaiting for the unique code. The bar will continue to flash for 2 minutesduring which time you can match the transmitter to the receiver.Hold the transmitter against the receiver right hand side, as shown(Pic 14), so that the white dot on the transmitter is touching theblack dot on the receiver (important!) for about 20 seconds toallow unique code to be transferred. Bars will increase up the displayscreen. When all 10 bars are shown they will flash to indicate thatthe unique code is transferred. When matched the transmitter mustimmediately be placed on the tank. If you are installing more than one Watchman unitplease wait 15 minutes between each matching.Pic 13Pic 148. FITTING THE TRANSMITTER(A) With a base - if supplied: Screw the transmitter (Part D) intothe base (Part E). Ensure the transmitter is vertical on top of thetank and level.(B) Without a Base: Screw the transmitter (Part D) and theweather seal (Part B) into the threaded hole.Ensure that the Watchmanunit is screwed into the baseor threaded hole (whicheverapplies) and that the threadshave not crossed, to give asecure seal.(See Picture 15)Pic 159.
